The test case is based on the example from the post-commit thread for: https://reviews.llvm.org/rGc9171bd0a955 This replaces the x86-specific simple-type check from: rL367766 with a check in the DAGCombiner. Adding the check isn't strictly necessary after the fix from: rL367768 ...but it seems likely that we're heading for trouble if we are creating weird types in this transform. I combined the earlier legality check into the initial clause to simplify the code. So we should only try the trunc/sext transform at the earliest combine stage, but we limit the transform to simple types anyway because the TLI hook is probably too lax about what it considers a free truncate. llvm-svn: 367834 |
